springboot启动gzip配置

server.compression.enabled=true
    server.compression.mime-types=application/javascript,text/css,application/json,application/xml,text/html,text/xml,text/plain

gzip压缩字符串

/**
         * 压缩字符串变成byte数组
         *
         * @param msg
         * @return
         * @throws IOException
         */
        public static byte[] setGzip(String msg) throws IOException {
            ByteArrayOutputStream byout = new ByteArrayOutputStream();
            GZIPOutputStream out = new GZIPOutputStream(byout);
            out.write(msg.getBytes(GZIP_ENCODE_UTF_8));
            out.close();
            return byout.toByteArray();
        }

gzip解压

/**
         * 解压byte数组
         * @param bytes
         * @return
         */
        public static String getGzip(byte[] bytes) throws IOException {
            ByteArrayOutputStream out = new ByteArrayOutputStream();
            ByteArrayInputStream inputStream = new ByteArrayInputStream(bytes);
            GZIPInputStream intput = new GZIPInputStream(inputStream);
            byte[] bytes1=new byte[1024];
            int result;
            while ((result=intput.read(bytes1))>0){
                out.write(bytes1,0,result);
            }
            return out.toString(GZIP_ENCODE_UTF_8);
        }
